' r Application filed rep'm 24,1903, Seria1No.417,2C1.

all whom it may concern: '1 Be it known that'I, BEnNDrA'; SWENSON,

a citizen of the United States, re's iding at Providence, in the countyof Providence and State of Rhode Island, have invented certain new anduseful Improvements in' Valve-Removers, of which the followingis.a'specification. 1 v I My invention relates to .devices for temporarilylifting the exhaust valve spring of a motor to permit the exhaust valvecotter pin as or key to drop out orbe removed; .and

. forits objects compactness which "permits pocket for road itsinsertion intoia garment use, simplicity, and cheapness.

To the. above ends essentially my invention consists in the'novelconstruction and combination of parts hereinafter described,

and illustrated in the'accorn'panyin'gdrawings, wherein 4 Figirres 1, 2andl3are side, top plan, and

rear .end views respectively of mynovel device, and Fig. 4, a plan ofthe bottom of the lower arm, or base.

Like reference characters indicate like" I parts throughout the views.-

My device is illustrated in conjunction with the usual exhaust valvestem, 1-,- spring 2, washer 3, cotter pin 4, upon which thewashernormally rests, cam rod 5, and cam 'rod guide 6, of an ordinaryvehicle motor.

' The remover comprises a lower or base arm, 8, with uprights 9, uponits 0p o'site sides intermediate its length connecte near their topswitha pivot pin, 10, traversing a lug; 11, upon the bottom of an upperarm, 12,. The

intermediate the len th of the latter.

' arm, 12, has acurve bearing projecti0n','13,

upon the upper face of its rear end, and through this projection and thearm itself is an-oblong longitudinal slot, 14. In, alinementzwith thisslot inthe end of arm 8, is a round threaded opening, 15. Passing,

through the slot and opening is a rod,'16, provided upon its .lower "endwith threads, 17, adapted to'Iengage in the threaded opening,

15, and fixed upon its upper end is a butterfly head, 18 the 'wholeconstituting an'adjusting screw for the ivoted arms, 8-, and 12. The

f the arm' 8 has a flat expanded portion,- 19, provided with a circularcavity,

20, upon itslower face, and a longitudinal slot, 21, extending inwardlysome distancefroni the outer end of the varn1, as shownin Fig. 4. Uponthe upper face of the forward end of the arm 1.2 is also a flat expandedor rounded portion, 22, provided with a curved cavity, 23, and alongitudinally disposed marginal-slot, -24, having a preferably nar-'rowed inner portion, 25.

The detailed construction of the arm portions, 19 and 22, are not toberegarded as exclusive, .but: the form thereof herein described hasbeen found best adapted to meet the requirements of a majority ofmotors.

The operation of my device isas follows;

the bearing portion or head, 19, of the arm, 8,

' rests 'uponthe guide, 6, whose top is within the cavity, 20, andthecam rod; 5, traverses the slot, 21. Or the head,'19, may rest uponthe head .of the rod, 5. ,The adjusting screw is next rotateddownwardly, the body ofthe head, .18, riding upon the curved projection,13, whereby 'a continuous bearing surfaceis 'affordedtheinut, 18,regardless of the angle [of the arm, 1'2. The'downward movement of thescrew gradually raises the end, 22, of the ar-m,:-. 12, which end hasbeen previously placed beneath the washer, 3, which is normallysupported by the key, 4. In'placing the end or head, 22, beneath thewasher,

the slot portiom 25, prevents interference with the key, .4, and theslot portion, 24, permits passage of the valve stem, 1. While the armsare distended as described, and'as shown in Fig. 1,;the key, 4, may bemanually through said. slot and having threaded engagement'with said 0em'ng with adjusting meansbearing on sai .curved'projections '2."In adevice'of the character described, the combination with an arm anduprights thereon intermediate its ends, a second arm pivotallymountedintermediateits ends on said uprights, the first-mentioned farmhaving'a bearing at one end anda threaded open- 'ing at the other end,a'second arm having a bearing at one end and a curved bearing projectionon its outer'face at ts other end amand the motor parts removed, andthereuponthe valve remover may be then'remove having an oblong lonitudinal slot and means passed through said s t and having threaded endof the rod.

3. In a device of the character described,

'the combination with an arm provided with a threaded opening in itsrear'end, of uprights upon the .arm intermediate its length,

a .second arm pivotally mounted intermediate its length in the uprightsand provided with an oblong opening in its rear end, bearing membersupon the forward ends of the arms,'.a rod traversing theoblong slot andprovided withithreads adapted to engage in the threaded opening, and anut fined to the 4. In a device of the character described, thecombination with an'arm provided with a threaded opening in its. rearend, of uprights upon the arm intermediate its length, a second armpivotally mounted intermediate its length in the uprights and providedwith an oblong openlng in its rear end, bearing members upon the forwardends of the arms, a curved bearing'projection upon the rear end of thesecond arm, a rod traversing the oblong slot and provided with. threadsadapted to engageinthe threaded opening, and a nut/fixed to the end ofthe rod and adapted to bear. upon the curved projection.

5. In a device of the character described,

the combination with an arm, of a bearin member upon one end of the armprovided with'a longitudinalslot, uprights upon the arm, a second armpivotally mounted in the uprights, a bearing member upon one end of thesecond arm provided with a longitudinal slot, and means at the otherends of said arms having one end in threaded engagement with one of thearms and the other end passed loosely through the adjacent end of theother arm for radially adjusting said arms. a
